Biometric Identification Technologies Get a Boost
With regard to biometric identification, the use of a lone identification technology leads to the creation of several false negatives and false positives. But, that might change if organizations or agencies began to implement what is known as bio-metric fusion. Bio-metric fusion involves the use of two constituent bio-metric identification technologies to arrive at better results.
For instance, using real-time facial recognition and speech identification can reduce the number of false positives or false negatives drastically. The evidence provided by a group of bio-metric identifiers has a very low chance of being questionable.
The problem with bio-metric identifiers is that they aren’t universal. For instance, a person who might have had his/her finger scanned for future identification might have lost it in an accident. This will lead to a failure if a single bio-metric identifier is relied upon. A combination of multiple bio-metric identifiers will counter the issue by looking at all factors such as voice patterns, iris scans etc.
Multiple biometric-identifiers also open up more options for the average person. A person who might not prefer iris scanning for personal reasons might be willing to switch to fingerprint scanning and voice recognition. Similarly, multiple bio-metric identifiers will also make it easier to handle groups of people who may not be suited for one particular system. For example, visually impaired people or people with speech impediments will have other identification systems in place to help them.
